Dutch direct air capture (DAC) startup Carbyon has secured €15.3 million ($16.9 million) in a recent investment round. The company has developed a patented, innovative technology that captures CO2 directly from the atmosphere. Their ‘fast swing’ technology enhances CO2 capacity, significantly reducing unit, energy, and project costs—key factors for large-scale deployment.
With this Series A financing, Carbyon’s total funding now exceeds €25 million ($27.6 million). This strong financial support will enable the company to develop its first engineering-scale demonstrators, begin commercial pilot testing, and prepare for an ambitious scale-up.
Carbyon now has three new investors: Siemens Financial Services, Omnes Capital, and Global Cleantech Capital, who are joining existing investors Invest-NL, Innovation Industries, Lowercarbon Capital, and the Brabant Development Agency (BOM).
Founded by Hans De Neve in 2019, Carbyon is developing DAC machines that utilise a patented, ultra-fast CO2 capture technique. This rapid process dramatically reduces the cost of their DAC machines, resulting in a significantly lower cost-per-ton of CO2 captured.
Over the past few years, the company has been refining its technology in preparation for scaling up. The recent investment will allow Carbyon to develop the first engineering-scale outdoor demonstrators and ready the company for market entry.
The initial models will be tested at the High-Tech Campus Eindhoven and sent to pilot partners for field testing. Simultaneously, Carbyon will prepare to scale up production to 50,000 machines annually by 2031, with plans to reach gigaton-scale capture by 2050.
“This new investment brings us much more than the financial resources to continue our growth. Our partners have the required manufacturing and scaling knowledge we need to rapidly but responsibly scale our technology. This consortium is a dream scenario and is highly motivating to continue with our mission,” said Hans De Neve.
“We are very pleased to be able to support Carbyon as it moves forward with the development of innovative and affordable technology to capture CO2 directly from the atmosphere” Andy Bown, Head of Negative Emissions Technologies Investments from Siemens Financial Services commented. “We stand ready to offer our financial expertise and access to Siemens’ broad portfolio of solutions to support Carbyon in its journey to deploy DAC systems at scale.”
